Article
Nutrient recovery from anaerobic digestion systems provides several side streams that are useful as biobased fertilisers (BBFs). A microcosm approach was employed to assess the short-term greenhouse gas emissions from a sandy-loam soil enriched with 18 BBFs in comparison with mineral fertilisers (urea and calcium ammonium nitrate). In total, 20 dif...
Article
The application of animal manure on agricultural land in the Netherlands is bound by legal limits to prevent the leaching of nitrogen (N) and phosphorus (P) to ground and surface waters. The surplus of animal manure is transported abroad at high costs. In this study, a full-scale cascaded membrane filtration system (GENIUS) comprising two decanter...

Phosphorus (P) is a finite resource and its reuse in organic fertilisers made from biowaste and manure should therefore be encouraged. The composition of solid organic fertilisers (SOFs) depends on the type of feedstock and processing conditions, and this may affect P speciation and hence P availability. Phosphorus speciation was assessed in eighte...

Humic substances are increasingly used as biostimulants in agriculture because of their supposed effects on nutrient uptake and crop yield. The objective of this study was to assess the effect of fulvic acid (FA) and humic acid (HA) addition with and without fertilization (N, P, K, S, and Ca) on (i) grass yield (Poa trivialis) and nutrient uptake a...

p>Peat is used as rooting medium in greenhouse horticulture. Biochar is a sustainable alternative for the use of peat, which will reduce peat derived carbon dioxide emissions. Biochar in potting soil mixtures allegedly increases water storage, nutrient supply, microbial life and disease suppression but this depends on feedstock and the production p...

Colloidal phosphorus (P) may represent an important fraction of the P in natural waters, but these colloids remain poorly characterized. In this work, we demonstrate the applicability of asymmetric flow field-flow fractionation (AF4) coupled to high resolution ICP-MS for the characterization of low concentrations of P-bearing colloids. Colloids fro...

In Nederland is de fosfaatbemesting op grasland via gebruiksnormen beperkt tot een evenwichtsbemesting. Om de verwachte daling van de fosfaattoestand van de bodem en de grasproductie te monitoren, deed Wageningen UR vana f 1997 een veldproef.
Chapter
In the Netherlands the P application standard including animal manure and P fertilizer has decreased to balanced P fertilization since 2015. Moving towards balanced P fertilization might affect grassland yield and quality, because soil processes might influence the P availability for plant uptake. In the short term, balanced P fertilization is not...
Article
Phosphate (PO4) and organic matter (OM) compete for adsorption to metal (hydr)oxides. Our objective was to quantify the effect of OM on PO4 solubility in forest and arable soil by desorption experiments and surface complexation (SC) modelling. We sampled different types of soil along an age gradient (≈50–2500 years) and from different depths (0–80...
Article
Manufactured metallic silver nanoparticles (AgNP) are intensively utilized in consumer products and this will inevitably lead to their release to soils. To assess the environmental risks of AgNP in soils, quantification of both their concentration and size in soil solution is essential. We developed a methodology consisting of asymmetric flow field...
Article
Colloids may facilitate the transport of trace elements and nutrients like phosphate in soil. In this study, we characterized soil colloids (<0.45 µm), extracted from four agricultural soils by Na-bicarbonate and Na-pyrophosphate, by two complementary analytical techniques; asymmetric flow field-flow fractionation (AF4) and X-ray absorption spectro...
Article
Iron-(hydr)oxide particles in soils have extremely large surface-to-mass ratios and are therefore considered to make up the largest fraction of the soils reactive surface area. Fe-(hydr)oxide particles are only a few nanometer in size when their surface-to-mass ratios are expressed as equivalent particle diameters. This suggests that Fe-(hydr)oxide...

Phosphorus transport from agricultural land contributes to eutrophication of surface waters. Pipe drain and trench waters from a grassland field on a heavy clay soil in the Netherlands were sampled before and after manure application. Phosphorus speciation was analyzed by physicochemical P fractionation, and the colloidal P fraction in the dissolve...
Article
Dit rapport geeft een overzicht van de omvang van de stikstof- en fosfaatverliezen en de hydrologische transportroutes van deze nutriënten uit grasland naar het oppervlaktewater en de speciatie van fosfaat in het afvoerwater. Het onderzoeksproject werd uitgevoerd op een zware klei, gesitueerd op een deel van een melkveehouderij bij Waardenburg in d...
Article
The aim of this work is to analyze the size-distribution and composition of nanoparticles in a water-extract of a podzol B horizon. AsFlowFFF coupled to ICP–MS and a UV/VIS detector was used for particle fractionation and simultaneous measurement of the composition of the nanoparticles. Detected nanoparticles were organic and mineral particles; the...
Article
Mining activities and industries have created nickel (Ni) contaminations in many parts of the world. The objective of this study is to increase our understanding of Ni adsorption and Nickel-Aluminium Layered Double Hydroxide (Ni-Al LDH) precipitation to reduce Ni mobility in a sandy soil aquifer. At pH ≥ 7.2 both adsorption and Ni-Al LDH precipitat...
